Ranked #714 - Sleeping Bags
March 16, 2009
I used this bag in the Lake Tahoe area on a perfectly clear night with temps in the 20's. Unfortunately, my sleeping bag got wet from frost and condensation. It makes me wonder why this bag is called a "winter" bivy when it can't even handle a mild night. Definately not worth the money.

Condensation and frost have nothing to do with a bag cover. They have to do with you dumping too much moisture into your sleeping bag and the area surrounding it. The only thing that prevents that effectively is a vapor layer.
